We motivate the formulation of market equilibria as a mixed complementarity problem (MCP) in order to bridge the gap between bottom-up energy system models and top-down general equilibrium models for energy policy analysis. Our objective is primarily pedagogic. We first lay out that the MCP...

We present a decomposition approach for integrated assessment modeling of climate policy based on a linear approximation of the climate system. Our objective is to demonstrate the usefulness of decomposition for integrated assessment models posed in a complementarity format. First, the...

In this paper we study political-economy determinants of the differentiation of environmental taxes between sectors. Using a common-agency model, we provide predictions on tax differentiation which are then tested using data from the German Ecological Tax Reform. As the reform is revenue neutral...

The formulation of market equilibrium problems as mixed complementarity problems (MCP) permits integration of bottom-up programming models of the energy system into top-down general equilibrium models of the overall economy. Despite the coherence and logical appeal of the integrated MCP...

Since January 1st the European Union has launched an EU-internal emissions trading scheme (EU ETS) for emission-intensive installations as the central pillar to comply with the Kyoto Protocol. The EU ETS may be linked at some time to a Kyoto emissions market where greenhouse gas emission...

Energy markets and energy-intensive industries in all EU member states – especially in Germany – are subject to a diverse set of policies related to climate change. We analyse the potential efficiency losses from simultaneous application of emission taxes and emissions trading in qualitative...

In the tax policy debate, differentiation of value-added taxes is often justified by distributional concerns. Our quantitative analysis for Germany indicates that such concerns are misplaced. We find that the abolition of VAT differentiation has only negligible redistributive effects. Instead,...

We analyze the economic effects of the differentiated targets for carbon abatement in six European Union member states. Our recursively-dynamic model includes a detailed representation of trade and energy consumption and incorporates optimistic projections for future energy markets provided by...

In the context of climate protection policy it has been suggested that global CO2 emissions should be reduced significantly (contraction) and that per capita emissions should gradually be equalized across countries (convergence). This paper uses a dynamic multi-region computable general...

Die Klimaschutzdiskussion wird von der Frage dominiert, welche gesamtwirtschaftlichen Kosten mit der Umgestaltung des Energiesystems zu klimaverträglichen Strukturen verbunden sind. Höhe und Verteilung dieser Kosten entscheiden darüber, ob sich umweltpolitische Strategien zum nachhaltigen...
